Impulsive Noise Suppression Using Fast Myriad Filter in Seismic Signal Processing

Myriad filter is widely used in impulsive noise suppressing, however, computing the high order filter polynomial effectively is still a big problem. This paper proposed a fast myriad filter computing method to speed computation. Compared with the classical myriad filter, the proposed method was much easier and simpler. The proposed fast myriad filter, was applied in impulsive noise corrupted seismic signal de-noising case, suppressed the noise and recovered the desired seismic signal effectively. And the estimated error of the fast myriad filter approached zero, it meant that the output of the proposed method was very close to the output of classical myriad filter. The experimental results verify the effectiveness of the proposed myriad filter.
